【摘要】 根据洛河、伊河河流及流经地区特征 ,选择具有代表性的断面 ,选用一维河流有限差分水质模型 ,计算洛河、伊河 1 995～2 0 0 0年主要断面污染物浓度 ,并对其进行评价。采用季节性肯达尔检验法 ,对计算出的洛河、伊河 1 995～ 2 0 0 0年主要断面污染物浓度进行趋势分析 ,并分析其变化特征及形成原因更多还原

【Abstract】 The one-dimension finite difference water quality model was applied to simulate the River Luo and the River Yi, tributaries of the Yellow River, in terms of pollutants concentration during the period from 1995 to 2000. The seasonal Kendall method was used for tendency analysis on the basis of the water data of the same period as well.更多还原
